audiophoolery or so.
Quadral Altan Mk 1 (Vintage 1983) came with Technics TH400 ribbon tweeter that I just measured with 5.4 Ohms (Fluke) and 5.0 Ohms (Keysight 1241b).
Bought those speakers yesterday for 100 Pesos/pair. Woofers are goners and need lotsawork.
The Tweeter from one of the Montans (a 4000 Bonnpeso/2000€ speaker) has the very same tweeters (that have been out of production since like 30 years ago). Measured at 4.5/4.0 Ohms on one and 5.0/4.7 on the other.
Put one of the tweeters from the Altan into the Montan, and lo and behold, the harmonics reappear and the sound becomes a hell of a lot better in an instant, with the result, that I consider one of those Montans fixed (at the expense of one Altan ...)
The other one needs reassembly and a tweeter transplant. The tweeter in the other Altan is apparently working as well.
Found replacement woofers for the Altan on the bay of fleas, currently bidding on them.
Refurbishing the tweeters will cost in the ballpark of 140 Brussels pesos apiece.
So, no matter how I turn or wiggle, the 100€ for the pair including the speakers were a good buy.
Once that is working I'll hook up my TA-E 86 pre- and Nakamichi PA-5E Mk2 power amp plus my external DAC and the external music streamer that I built yesterday.
And have some decent sound quality in the flat which is up north near the coast (North Sea, not Baltic ...)
Looking at the difference in measurements I am somewhat underwhelmed. .4 ohms difference ? REALLY ?
Between a Fluke 179 and a Keysight 1241B ? There is something wrong here, too bad I did not bring the Gossen as arbiter.
May indeed try to find a halfway reasonable somemoredigits DMM ...
